About the Airtac SAI100 Standard Air Cylinder SAI100X375S
The AirTAC SAI100X375-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It delivers a robust push force of 3927 N and a pull force of 3681 N at 0.5 MPa, making it well-suited for moving substantial loads over a 375 mm stroke. The extruded aluminum barrel eliminates tie-rods, providing a clean profile that drops directly into standard ISO 15552 mounting interfaces.
This specific configuration includes a piston magnet for proximity sensing, allowing seamless integration with CMSE or DMSE reed switches mounted into the dual sensor grooves on the barrel. The standard carbon steel piston rod provides excellent tensile strength for industrial environments, while adjustable air cushions at both ends absorb kinetic energy to protect end-of-stroke components.

Where the Airtac SAI100 Standard Air Cylinder SAI100X375S Is Used
Heavy Stamping
Provides the 3927 N push force required to actuate heavy stamping presses and form metal components securely over the 375 mm travel.
Pallet Diversion
Pushes fully loaded pallets off a high-throughput conveyor line, utilizing the adjustable air cushions to decelerate the 100 mm bore smoothly.
Automated Clamping
Holds large workpieces stationary inside machining cells, using the integrated magnet and CMSE sensors to confirm clamp engagement to the PLC.
Is the Airtac SAI100 Standard Air Cylinder SAI100X375S the Right Cylinder?
Selecting this 100 mm bore over the smaller 80 mm variant significantly increases thrust, stepping up from 2513 N to 3927 N at 0.5 MPa. If your application requires even higher force, the 125 mm bore offers 6136 N. At a 375 mm stroke, the unsupported rod length is substantial; side loads can cause rod-bearing bending and premature wear. To manage this, implement an external guide rail or use a guided cylinder to absorb lateral forces.
Because it is a double-acting pneumatic cylinder, the SAI100X375-S relies on continuous air pressure to hold its position. If air is exhausted or the valve centers, the piston will drift. For applications requiring fail-safe load holding without live pressure, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. This model features a PT tapered port thread and is fully dimensionally interchangeable with other ISO 15552 cylinders.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAI100 Standard Air Cylinder SAI100X375S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder generates a push force of 3927 N and a pull force of 3681 N. If pressure is increased to 0.7 MPa, the push force rises to 5497 N.
Yes, the SAI100X375-S is a true ISO 15552 profile cylinder. Its mounting dimensions are standardized, making it a drop-in replacement for other ISO 15552 cylinders. You must match the 100 mm bore, 375 mm stroke, and PT port thread.
